A power outage can disrupt your entire home. The lights go out, appliances stop running, and your daily routine is interrupted. If you rely on electricity for work, comfort, or medical needs, even a short outage feels disruptive.
The Generac Guardian 22 Kw Standby Generator helps you avoid that. It keeps your home powered automatically, so you can stay comfortable and keep everything running during an outage.
This guide explains its standout features, benefits, installation process, and what to consider before adding one to your property.
What Is a Standby Generator?
A standby generator automatically supplies electricity when the grid goes down. It starts on its own and runs until utility service is restored. You don’t need to refuel it or connect extension cords during an outage.
Unlike a portable generator, a standby system is installed permanently outside your home. It connects directly to your electrical panel and your natural gas or propane line. This makes it reliable and ready whenever it’s needed.
Choosing a standby generator keeps your home powered without interruption. Lights stay on, heating and cooling keep running, and electronics remain protected. That’s why many people prefer it over smaller portable units.
Key Features of the Generac Guardian 22 Kw Standby Generator

Installation Process of the Generac Guardian 22 Kw
Installing the Generac Guardian 22 Kw is a detailed process that helps achieve reliable and safe operation during a power loss. Working with a professional like W. Danley Electrical guarantees compliance with codes and proper setup.
Site Selection and Preparation
First, select a stable, well-drained outdoor location away from sprinklers, downspouts, and standing water. The site should provide at least three feet of clearance from walls to allow airflow and maintenance access. Clear any vegetation and level the ground. Install a base of crushed stone or pea gravel, then place the composite pad where the generator will sit securely.
Unboxing and Positioning
Next, unbox the generator and include a 200-amp automatic transfer switch. Use proper equipment to move the unit into place on the composite pad. Take care to align it correctly for wiring and fuel connections.
Fuel Connection
The generator connects to an existing LP or natural gas fuel line with a shutoff valve and regulator. Local codes must be followed for piping and fittings. The fuel inlet is located on the right rear of the generator, about ten inches above ground level.
Electrical Wiring and Transfer Switch Installation
Install the automatic transfer switch near your home’s main electrical panel. This allows for short, efficient wiring runs. Connect the generator to the transfer switch using flexible conduits. Run wiring into the main panel while sealing wall openings to prevent moisture entry. Ground the unit using an eight-foot rod connected to the chassis.
Battery and Accessories Installation
Inside the generator, install a 12-volt starting battery. Generac recommends a Group 26R 540 cold cranking amps (CCA) minimum wet cell battery. This supplies reliable starting power even during extended outages. Optional accessories, such as a maintenance kit or cold weather kit, can also be added at this stage.
Initial Setup and Testing
Program the generator using the multilingual LCD. Set your preferred language and review startup settings. Perform a full startup test to confirm that the generator starts automatically, transfers power, and supplies proper output. Test the Mobile Link Wi-Fi connection to monitor real-time operating status from your smartphone or computer.
Permitting and Compliance
Obtain any required permits from your local building department or homeowners association before installation. All work must comply with the National Electrical Code and local regulations.
Since this process involves fuel, electrical, and code compliance, it should always be performed by a licensed professional. W. Danley Electrical is a trusted provider of Generac Guardian Series home standby generators. Their team handles the generator installation so your home stays protected during outages.
How to Maintain a 22 Kw WiFi Standby Generator
Regular maintenance keeps the Generac Guardian 22 Kw dependable through the rigors of generator use. Routine care helps it perform during unexpected power loss without problems. Many choose annual service to keep their unit ready.
The multilingual display shows maintenance reminders and alerts if service is needed. You can also use the Mobile Link feature to monitor status and updates remotely from a smartphone, tablet, or computer.
Basic upkeep includes checking oil levels, replacing air and oil filters, and cleaning the aluminum enclosure. A technician can test voltage output and inspect the automatic transfer switch connections during a scheduled visit.
The area around the generator should stay clear of plants, debris, and moisture. This protects the aluminum housing and allows proper airflow. Keeping it clean also extends the life of the enclosure.
